zetec headgasket change
RichardK - 25/3/11 at 10:35 PM

Convinced the headgaskets gone on my zetec, how hard are they to do and how many special tools are required? defo burning coolant as it not in the oil and no hoses are leaking. Plenty of water out of the exhaust though. And coolant gets very dirty very quickly.

Havent got 2 or 300 quid to throw at another engine which maybe worse mechanically than this one. But could find the money for a gasket.

Anyone done one, How hard was it???

Cheers

dunno mate but happy to give you a hand


RichardK - 25/3/11 at 10:42 PM

Thinking about trying that repair liquid? But thats about £30


ashg - 25/3/11 at 11:01 PM

you can get a gasket kit for £25

then a head skim is another £30

so £55 and a days work and its fixed properly.

I know what you mean Ash but it never stops there does it, new head bolts, rocker gasket, special tools for holding cams in place and that just the stuff off the top off my head.

Can get seal stuff for a tenner but the stuff I've used before steel seal is near £30 but it is the best stuff.

Dunno, dunno, still thinking....

i have never used a special timing tool in my life. mark everything up or find a way of locking the cams and crank. remove the head skim it and fit new headgasket. if your really short on cash you will get away with reusing the old head bolts as long as they haven't already been reused.

what is the point of bodging it. it will only come back and bite you on the ass when your out on a run.

edit...

rocker cover gasket comes in the kit

Thanks ash, I'll take a look, think those are for a silvertop, my engine is a 2000 but should be similar money so ta.

Ive just done mine. Get the head skimmed or you will be doing it again as I am.

Tools wise just over a tenner will buy you the proper cam tools and the zetec is a nice easy engine to work on. Only other special tool would be an e10 female torx's bit for the cam caps and an angle gauge for the head bolts gives peice of mind.

Thanks mate, got everything except the pin kit then, just ordered it so thanks for the link.

I'm going to try a bottle of steel seal first and keep an eye on it, have used it before on a mates car and it worked great last time so we'll see, it's fairly obvious because of the extra steam that get generated.

Yeh will get the head skimmed if I end up taking it off, thanks for the tip, as I would have probably tried to "risk" it like you.

Cheers

big_wasa - 26/3/11 at 08:36 AM

I wouldnt bother with the goo. I put mine of as I was usure on who to get the head skimmed by. Found a top place just up the road from a recomendation on here.

£30 cash and they even asked If I could wait a whole 12hrs for it


RichardK - 26/3/11 at 08:50 AM

Warren, do you mind me asking where you got your gasket set from, having a little trouble finding a complete kit.

(1) Don't assume the head needs skimmed ---- unless the engine has been really cooked or the waterways are badly corroded, just carefully check the head. If the waterways are corroded at the head surface you need to get it TIG welded and skimmed.

(2) Usually OK to reuse stretch bolts up to about 3 or 4 times --- the bolts are stretched ie operating beyond the elastic limit in the "plastic zone" but this is well below the range at which failure (ie "necking" occurs. This actually increases the elastic limit of the bolt, but failure load remains the same. On re-use subsequent tightening of the bolt, the bolt will only start to go into the plastic zone again when the bolt is very very close to the original final fully tight load (either by angular tightening or torque wrench). The amount of plastic stretching (permanent set) added on second or third tightening will be tiny.

(3) the really crucial thing is to get the first torquing down stage absolutely spot on otherwise all the subsequent angular tightening will be highly inaccurate. Make sure the bolt threads are very clean and undamage, lubricate with kerosene or WD40 but you must allow the threads to drip dry before screwing them in.

Thanks BT, good advice as always, cheers buddy.

Just one tip , DO NOT use the cam locking tool to undo the Torx bolts holding the cam sprockets , have seen cams broken when this has been done . Make, buy, borrow or steal a sprocket locking tool ,or use a spanner (think there is a hexagon on each cam)

I usually use mole grips to hold the cams still to undo the pulley bolts. I've seen engines that have been done without slackening off the pulleys and they don't run perfectly afterwards so make sure you do it when you time it back up.

No need to undo the cam sprockets is there?

Yes, especially if the head is skimmed as valve timing will be altered and also the tensioning of the timing belt should be done with the pulleys slackened


RichardK - 26/3/11 at 12:28 PM

Mmm, I was thinking if I marked everything up then just put everything back in as they were then I wouldn't need to take the pulleys off, except if the head needs a skim though.

Is my plan not going to work and they need to come off then for defo??

Cheers

Rich

Steve you sobered up yet?


coozer - 26/3/11 at 12:37 PM

Dunno what u mean Right as rain here.....


lotusmadandy - 26/3/11 at 06:40 PM

As above,i have done a couple of zetec cam belts.Never slackened
the cam pulleys and had no bother.

Andy


rusty nuts - 26/3/11 at 07:47 PM

Two ways to do the job , one is the right way! The Ford way is to slacken the pulley bolts . Decide for your self which way you do it !


big_wasa - 26/3/11 at 08:04 PM

Ive done a few zetec belts. Before I undo the cam bolts I check the timming and turn it over a few times. It can be upto half a tooth out. It can also be spot on.

I got my last gasket from femi on here. I normally just nip into the local factors. I only needed the head gasket and bolts. I dont like re using them for the sake of a tenner.
